Modified BIOS for Microserver N40L enables hidden features

Recommended Posts

Macca

Thanks Guys for the response but I'm still stuck.

 

A few points...

 

Setting to USB boot in BIOS is pointless when you are going to flash the BIOS with a new ROM...the new ROM on boot up will use its default settings on boot up anyway. It seems that USB is default in any case.

 

Following on from your suggestions I've now tried a few USB keys from various manufacturers but its still the same. Looking on one of the links they suggest using a max 2Gb USB key too so I tried that as well. I've also tried removing all discs and then switching on but still the same red light from switch on.Ive also tried my factory BIOS reset USB key that was made beforehand....and I also made another one fresh on another USB key....but still no joy.

 

Seemed a bit strange none of this was working so I grabbed a USB key which lights when up active and plugged that in but it didn't light up. I then tried an HP optical USB mouse in one of the other USB sockets and that doesn't light up when they normally they light up red....so its a possible power to USB socket fault and that is maybe the reason why the USB key to do BIOS Flash wont work.

 

I've had the Motherboard out , re seated the RAM and made sure cables are all plugged in.

 

Ascskenny says The red light looks like a critical error fault but its only come as a result of doing this BIOS mod (whether its completed on not completed I dont know) . The server and the BIOS was fine before that.

 

Joe...you've very kindly cleared up what actually happens during the BIOS flash after a start up and I found that extremely helpful..unfortunately I saw none of that as the display suddenly went blank about 20 seconds after switch on, the server then rebooted itself and on restart came up with the red light. The mains was constant throughout and there was no power blip at all. Now If I try to reflash it fails.

 

So at the moment I am still stuck on POST (therefore I cant get into BIOS at all ) with no svga /vga output to display and what looks like no power or usable USB sockets.

In the timeline I saw – the 20 seconds mark was about when my stock 2GB memory was detected – the first 37 seconds after energizing it appears the MicroServer spent the time checking/initializing itself and it wasn’t until the 37-9 seconds mark that the DOS Command Shell executed and began loading the ROM Image – i.e. when it actually began flashing your BIOS.

 

This timeline was on my Stock MicroServer with only the Stock 2GB RAM module, no drives of any type attached to any SATA ports (I pulled the Stock 250GB HDD and my machine came with no ODD) and no PCIe Cards were installed. Only the Monitor, Keyboard, Mouse, and USB stick (with the BIOS-MOD) were attached (the NIC was not connected). If you had anything else in your Machine I would expect the timeline to be extended out.

 

So if your system failed at about 20 seconds I would speculate that it failed while checking out & initializing devices on your System Board and then those devices attached to your System Board.

 

That would appear to narrow the problem down to your System Board while it was initializing and had nothing to do with your attempt to flash the BIOS. The screen flash and self-reboot you saw at 20 seconds adds weight to my suspicions about the System Board & possibly RAM.

 

If you had upgraded the RAM earlier – then the only remaining test that I can think of (since you’ve re-seated your RAM and other board connections earlier) is to consider removing the upgrade RAM & re-installing the Stock 2GB RAM stick and pull all drives attached to your SATA Ports and any PCIe Cards and try a System Start in that minimal configuration.

 

If that doesn’t get you past POST then follow CSKenney’s 2nd option -- to Call HP and RMA your System Board.

 

It’s possible HP may also have ideas on other things to check out. Good Luck & Let us know what you learn from HP.

 

Pages 82-83 of the HP ProLiant MicroServer Maintenance and Service Guide has a few things to look at regarding failures during POST.

I thought (was hoping) the N40L and N36L BIOS was actually the same, is this not the case? (Based on the topic of this thread)

I should own an N54L within about a week or two, so I was kind of hoping to BIOS mod that.

 

UPDATE:

My N54L has arrived and has shipped with BIOS 041 "07/29/2011" I can take a photo of the board shortly if anyone is interested also?

Actually nope, this totally worked - the NEC USB 3 controller is listed for example, onboard audio - all kinds of things which don't exist inside the little box. Now to figure out what to enable to get full speed SATA ports and port multiplier working.

Hello

 

Sorry I have not read this entire post.

 

However I have followed the instructions to install the mod BIOS. So I can move the OS hard drive up in to the optical drive bay on port 5.

 

I am also wondering if the mod BIOS makes it possible to enable S3 Sleep mode? I have currently got the Microserver N40L to hibernate but it would resume faster from S3 Sleep

 

Thanks

No S3 sleep on the Microserver. For further details....read this entire topic.

      Hey guys,
       
      As of June 2020, what are the latest versions of firmware for HP Microserver Gen8 to be installed on the system itself? Also do any other components have updatable firmware/os-independent software?
       
      So far my list is as follows:
      BIOS - J06 (04/04/2019) iLO 4 - v2.73 (11/02/2020) Intelligent Provisioning - v1.71 (20/02/2019)  
      and I guess the following could also be added (although both out of date):
      Smart Update Manager (HP SUM) - v8.1.0 (21/12/2017) Service Pack for ProLiant (06/11/2017)  
      Date formated as DD/MM/YYYY.
       
      I believe all the B120i Smart Storage stuff is part of Intelligent Provisioning.

      I have a simple question about my BIOS from iLo4. Look at the picture and you will see a difference in the System ROM and Backup ROM dates.

      Hey guys,
      Not sure if this is the correct section to post this, but in a bit of a pickle after attempting to flash my HP Microserver N40L to the modified bios last night.
       
      The story goes - I've had myN40L microserver for the past few years running Windows 8.1 and acting as a media server for the house. I recently upgraded a laptop I have so had a spare Samsung 840 EVO 120gb SSD that I thought I'd throw in the microserver as the boot drive. 
       
      I ghosted the existing windows install (which was on a 250gb mechanical hard drive) over to the SSD, rebooted the computer and everything was working file. When I checked the performance of the SSD using the Samsung Magician software it indicated thatt the SSD wasn't running at full speed due to AHCI being disabled. I then did a bit of research and found that SATA port 5 (normally meant for an optical drive) that the SSD was connected to doesn't run at full speed and in IDE mode. I read that the modified bios that's floating around for Microserver's can fix this.
       
      So I flashed the bios to my machine however now when I boot up it gets to the loading screen for windows and then errors and reboots. This boot loop just continues constantly with no way to get into windows.
       
      I've tried setting the hard drive mode to both IDE and AHCI in BIOS with no success, I've reverted the BIOS back to default settings, took out the CMOS battery overnight, tried to re-flash back to default HP firmware, re-flashed the modded BIOS with no drives in the server and even run the windows 8 startup repair with no success whatsoever, it just continues to error and boot loop.
       
      I did leave all 4 of my other SATA hard drives in the machine when flashing the modded bios originally so don't know if this affected it. I wish I'd just left the original BIOS on there now.
       
      Is there anything I can try to fix this? I'd really prefer not to have to reinstall windows 8 as it took me awhile to set everything up for media (Sonarr, CouchPotato, iTunes, Serviio etc).
       
      Any help is greatly appreciated.
       
      Cheers Benny

      Bought this ML10v2 a few months ago and have been hitting wall after wall, frustrated- putting it away for a few weeks, and then trying again. I can not get it to boot from a USB and have not figured out how to recognize and identify drives!
       
      I have gotten iLO4 working with a valid key, I have updated the SPP, registered on who knows how many HP/HPE pages, looked through the documentation- but still can't get the machine to boot to my Linux USB for installation.
       
      This seems like a basic step, but I've kind of lost my objectivity at this point and wanted to ask for help. Is there something I need to do in iLO4 to have it recognize the install media or my drives? I can't seem to make sense of the Virtual Media field.
       
      I want to install Ubuntu 16.04 Server- HP/SPP says it supports Canonical. How do I get the machine to 1) open into BIOS? is it F2/F9/F10/F11 during boot? My POST sequence never seems to get past 10%, and then 2) recognize my hard drives, no matter what number SATA cable, it doesn't see them. I can only open the iLO4 manager from another computer on my network, so I can't open it on local host like the (very helpful) Joe Stutsman videos and instruction guides suggest.
       
      Anyhow, any input on this configuration would be appreciated. I know I'm missing something, but want to exhaust all options before I return this.
